CHRISTOPHER J'. MEYER, OF MILWAUKEE, WISCONSIN, ASSIGNOB TO EYINRUDEMOTOR COMPANY, OF MILWAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN.

TRANSOM-CLAMPING BRACKET.

Specification of Letters Patent.

Application filed March 22, 1915. Serial No. 16,143.

To all whom it may concern:

Be it known that I, CHRISTOPHER J row boat motors.

The transoms of row boats vary in form and are frequently more or lesswarped or irregular in surface contour. On the other hand,detachable'row boat motors are de signed to be conveyed from place toplace and secured to different row boats at different times.

The object of my invention therefore is to provide a form of clamp whichwill engage any style of transom and which Wlll facilitate binding themotor driven propelling mechanism thereto with absolute r1- giditynotwithstanding irregularities in the form of the transom or in itssurface contour.

In the drawings Figure 1 is a perspective view of a detachable row boatmotor provided with a transom clamp embodying my invention.

Fig. 2 is a detail front elevatlon of the transom clamp showing afragment of a transom engaged thereby.

Fig. 3 is a side elevation with a fragment of an engaged transom clampillustrated in section.

Like parts are identified by the same reference characters throughoutthe several views.

My improved transom bracket is organized with a view to securing a threepoint bearing upon the rear face of the transom and clamping bearings attwo pomts upon the front face of the transom, the clamping bearingsbeing preferably so located as to substantially equalize the pressure ateach of the three points where bearing is had upon the rear or outertransom face. The head A of the bracket is adapted to rest upon the topof the transom in the usual manner and is provided with upwardlyprojecting posts B, suitably apertured to receive the connecting boltsC, whereby the bracket may be connected with the motor frame. The rearportion of the head 15 provided with a pair of arms, which extenddownwardly from the respective sides and convergingly at their lowerends to a lower clamping plate C having a knurled en- I gaging innerface. The upper end of each of these arms has a bearing portion D,adapted to engage the transomE near the upper margin of the latter, thesaid bearing portions being extended inwardly and connected togetherforming with the inner face of the head A a right angular seat forresting upon the transom edge. Below the bearing members D, each of thearms is offset rearwardly out of contact with the transom E, asindicated at F. The converging lower end portions F of the arms have anangular forward pitch and support the bearing member 0 in position toengage the transom E simultaneously with the engagement of the portionD.

It will be observed that the two upper bearing portions D and the lowerbearing portion C are at the respective angles of an approximatelyequilateral triangle and the bracket will therefore automatically adjustitself to the contour of the rear face of the transom, when appliedthereto in the position illustrated in Figs. 2 and The downwardlyprojecting arms are preferably provided with rearwardly projectingreinforcing webs G, whereby suflicient rigidity is imparted to the armswithout excessive weight. A pair of segmental arms H extend rearwardlyfrom the member 0 and are adapted'to engage a supporting block I,whereby the propeller supporting shaft J may be held in a verticalposition. The members I and J, however, form no part of the presentinvention and are not claimed herein.

' The front portion of the bracket head A is provided with a pair offorwardly and downwardly projecting arms K with which clamping setscrews L have threaded engagement adjacent the free ends thereof, whichends are connected together by a brace N which is parallel with the saidhead A. These set screws are provided with ordinary swivel heads Madapted to bear upon the inner .or front face of the transom. It will beobserved that the clamping heads M engage the transom below the pointsengaged by the bearing members D. The pressure exerted by the clampingheads M is along lines which, if projected, would intersect PatentedAug. 14, 1917.

the ofl'set portions F of the rear clamping arms. The specific positionof the clamping heads M, however, is not essential to my invention,except that it is very desirable that they be so located as todistribute the pressure upon the three rear bearing points. I claimv 1.A transom clamping bracket for boats comprising a head adapted to restupon the top of the transom, opposite upright reinforced posts upon saidhead adapted for pivotal connection with a boat propelling motor, a pairof arms extending downwardly and convergingly from the opposite sides ofthe head, a substantially rectangular clamping plate connecting thelower ends of the said arms having a lmurled inner engaging face, and aset of clamping set screws supported from the head in a position toengage the transom between said screws and arms, the said arms beinprovided with bearing portions adjacent t e1r upper ends connectedtogether inwardly angularly disposed with respect to the inner face ofthe said head and adapted to engage the side of the transom when thedevice is operatively positioned, the said arms being ofiset from thetransom between said clamping'plate and bearing portions, the said setscrews having swiveled clamping heads located to substantially equalizethe pressure upon the bearing portions of said arms and upon the saidclampin plate.

2. A c amping bracket, including the combination of a head portionhaving a rear pair of depending arms arranged to engage the uppermargmal portion of the transom on the rear side, and offset therefrombelow the points of engagement, the lower portions of.

said arms converging downwardly, a clamping plate connecting the lowerends of said arms, and adapted to bear upon the middle portion of theboat transom, a forward pair of relatively short arms depending from thehead out of contact with the transom, set screws at the lower ends ofsaid forward arms projecting rearwardly'in the direction of the transom,and provided with clamping plates adapted to engage the front surface ofthe transom at points above and laterally ofi'set from the area engagedby the first mentioned clamping plate on the rear 'surface of saidtransom, whereby when the set screws are turned to clampin position therear face of the transom will en aged at three bearing points, and thefront ace will be engaged at two' bearing areas, with the front bearingarea disposed intermediate of the upper and lower bearing areas of therear arms to equalize and distribute the bearing pressures,substantially as described. v In testimony whereofI afiix my signaturein the presence of two witnesses.
